ELECTRIC BELT.

SPECIFICATION forming part of Letters Patent No. 455,680, dated July '7,1891.

Application filed February 24, 1891. Serial No. 382,329. (No model.)

To all whom, it' may concern.-

Be it known that I, CHARLES A. BoGARDUs, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Electric Belts, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to electric belts designed to be worn as a remedialagent.

`My object is toproduce a belt composed of multiple battery-cellsconnected together by suitable wiring, butnot hinged together, andprovided with a positive and a negative pole upon the respective ends,to which the Wiring is connected, said cells consisting of sheets ofzinc folded over at one end, a covering of absorbent material, and wirewound around over the absorbent as many times .as desired, then bentinwardly from the outermost coil, then twisted close to the edge of thecell-body, then bent outwardly and hooked over inwardly, and having thepoints of the hooks bent outwardly at substantially a right angle, saidhooks entering the ends of the fold and the outer ends lying between thebody and the fold, so that the hooks' cannot turn as hinge-pintles northe cells turn on the hooks, and when a sufficient number of cells areso secured together the poles are connected to the ends of themultiple-cell battery.

` My invention consists in the several novel features of construction,which are hereinafter specifically described, and are set forth in theclaims hereunto annexed. It is constructed as follows, reference beinghad to the accompanying drawings, in which- Ihigure l is a sideelevation of a series of' battery-cells connected together and havingthe poles connected to the ends. Fig. 2 is an edge elevation of one celldetached. Fig. 3 is an elevation of the opposite face vof a cell' fromwhat is shown in Fig. l. Fig. Liis a vertical transverse section of acell on the line in Fig. l. 1

A A are the cells, and a Z) are the positive and negative polesconnected to the extremi ties of the series of cells. Each cell consistsof a iiat sheet of zinc c or analogous metal,

onto the body of the sheet. A sheet of proper or suitable absorbent e isth en wrapped around the sheet, substantially as shown, with its l endsoverlapping. I then take a strip of copper 7L or other proper metallicconductor and apply it to the absorbent. I then wind an annealed wire 7caround the cell-b odylengthwise in contact withcboth the paper and thestrip 7L, but not with the zinc, drawing the ends inward tosubstantially the center, then twist them, as at m, which tightens thewire around the cell and prevents the coils or winds from slipping' offon the ends. I then' bend the ends outwardly from the twist, theninwardly, forming the hooks n, and then forward, creating the arms o.-Ithen insert the hooks and arms into the space between the body of thezinc and thevfold-over, the arms being longitudinal to the zinc andcell. I then crimp the zinc inwardly, as at 2J, and this not only bringsthe arms and hooks into perfect electrical contact with the zinc, butalso locks the hooks and arms, so that they cannot turn nor act as thepintles of hinges between the cells'and cannot accidentally unho'ok, soas to break the circuit. IVhen thus a series of cells are connectedtogether and the poles are connected to the outermost cells, I have abattery of multiple cells not hinged together and not pliable oriiexible, except as the connecting-wiresare bent. This battery is dippedinto an acid solution, saturating the absorbent and creating an electriccurrent through the cells from pole to pole, the copper strip 7Loperating as the positive connections of each cell to the wires.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. VIn an electric belt, the combination of a flat zinc folded over onone end, a covering of absorbent material, a wire wound around over theabsorbent, then `twisted at one end of the zinc and absorbent, then bentoutwardly from the twist, then bent inwardly, forming hooks, and bent toform forward-projecting points.
